I always try to get two of everything I buy. I will smoke one and let the other sit a while, smoke and compare.
I haven't really aged enough cigars to say anything about the cello on or off. I don't think it would make a big difference. I don't think its as important as the condition in which the cigar is stored.
In my short year of smoking, I have noticed that some cigars are better fresh, and some with age. The hard thing to figure out is it the aging that made the cigar better or is it my taste changing.

Good luck
